One
hesitates to sully this image with negative mentions, but steep-sided fiords do
present a real and present danger in the form of rockfalls and rockfall-generated
waves. “Fiord tsunami” I call the latter, however some find this liguistic mixture
ludicrous as ‘lutefisk sushi’.

Terms
aside, rockfalls and rockfall waves are serious business -- many dozens have
occurred in historical time. The latest
fiord tsunami happened in 1934 just outside of the town of Tafjord. Waves rose
up to 62 meters elevation there and 41 persons perished.

The
greatest rockfall threat looming today lies on Akerneset Mountain, flanking Sunnylvsfjorden 23 km west of Tafjord. There, a set of ominous cracks gape 900 meters
above sea level. The cracks are thought
to bound a sliver of mountain maybe 60 million cubic meters in volume that,
like others did before, will surely fall into the fiord someday.

My
computer simulations in the movie above predict that a fiord tsunami 100 m high
would be sourced from a Akerneset rockfall.
Not good news for Hellesylt and Geiranger, two pretty towns nestled just
four and eleven minutes away by tsunami. The truly scary part of the story is
that the crack widths are expanding by 3-20 cm/year.

As
you might expect, scientists now closely monitor the landslide region with a
battery of instruments. Their hope is that a pre-failure increase in the rate
of crack expansion could provide prior warning of an impeding slide perhaps
days in advance.

The
notion of “Furious Fiords” has not escaped the attention of big-budget moviemakers
as fodder for a docudrama/disaster flick.
Recently a Norwegian film company released the movie titled “Bolgen” (Norwegian for “Wave”) staring this very same
fiord tsunami. Take a look at the teaser…

You really did kill that illustration, very creatively and interestingly done. You are one awesome and gifted dude, like some of the students at BookWormLab reviews who are fond of doing creative simulation samples for their project.

i like reading and writing,also i love shopping at ennbuy.com,you can choose chlothing,shoes,sports and so many fashion things for man and women，and Thanks for providing such useful information.It is something to be proud.

This simulator video of showing fiords tsunami is very good creative presentation, as i have seen it before from rushessay com reviews blogs, and this video show the great danger for that city if anything like tsunami hit that place when can clearly see the falling of rocks and how much destruction those falling rocks can create in that city and change the face of the city in seconds time.

Awesome illustration of furious fiords. You are indeed very talented when it comes to simulation presentations, just like how the staff of BuyEssayOnline.org reviews did their simulation project in the past.

These are some really terrifying scenes shared in the video. I have watched the video and it is quite hard to believe. Unbelievable scenes are being recorded on the same and I am wondering about how they managed to capture those scenes.best internet service consumer triple play

Thanks for taking the time to discuss that, I feel strongly about this and so really like getting to know more on this kind of field. Do you mind updating your blog post with additional insight? It should be really useful for all of us. MCA Loans
